HEEL-RISER FOR RAILWAY-FROGS.

SPECIFICATION forming part of Letters :Patent No. 715,750, datedDecember 16, 1902. Application filed May 3l. 1902l Serial No. 109,712.(No model.)

The object of my\invention is to utilize steel rails in the productionof a durable,

stable, and comparatively inexpensive heelriser for railway-frogs. Thisand such other objects as may hereinafter appear are attained by thedevices illustrated in the accompanying drawings, in which- Figure lis aplan view of a heel-riser. Fig. 2 is a side elevation thereof'. Fig. 3is a crosssectional view on the line 3 of Fig. 2. Fig. 4 is a like viewon the line 4 of Fig. 2. Fig. 5 is a cross-sectional view, correspondingto the line 3 of Fig. 2, of a modified form of my device; and Fig. 6 isa sectional view, on the line corresponding to line 4 of Fig. 2, of thesame modified form of iny'invention.

Like letters of reference indicate the same parts in the several figuresof the drawings.

In Figs. 3 and 4 I have shown a T-rail reversed and having its head Aand web B embedded in a casting of iron C, which has been cast aroundthe rail so as not only to securely hold the head and web of the rail,but also so as to support the anges D and provide a broad base for theheel-riser. Preferably the casting C is cast of such form and dimensionsas not only to provide a firm base for the heelriser, but so as to litsnuglybetween the adjacent rails of the frog, to which the heel-riser issecurely anchored by means of bolts passing through the bolt-holes Einthe heel-riser. It will thus be seen that I obtain a compositeheel-riser having a steel wearing surface or face backed by a mass ofcast-iron to which the steel face is securely attached, the riser alsoVhaving a wide, stable, and cheap base of cast metal. This form of mydevice not only enables me to use a commercial form of steel, which maybev readily obtainable at times when an order for a special form couldnot be filled for many months, `but, in view of the fact that the railis reversed, so that the under side of its flange is used for thewearing-surface of the heel-riser, it does not matter that the head ofthe rail may have been worn, and so I am enabled to use discarded rails,which can be readily brought to the desired shape with a minimum ofmanipulation and can be obtained at much less than the cost of new railsor of even steel billets.

While I prefer the stability aorded by my device when constructed asshown in Figs. 3 and 4, the construction of the riser may be modified byfirst shearing off the head of the rail in slitting-rolls or in anyother suitable manner, in which event theriser will be constructed asshown in Figs. 5 and 6, thereby saving the material composing the headof the rail, which may be used for any other desired purpose.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. As a new article of manufacture, a heelriser comprising a steel railreversed and embedded in cast metal, the under surface of the base ofthe rail being exposed to form the upper face of the heel-riser,substantially as described.

2. As a new article of manufacture, a heelriser comprising a castinghaving the web of a steel rail embedded therein and having the undersurface of the base of the rail exposed to provide the upper face of theriser, substantially as described.

3. As a new article of manufacture, a heelriser comprising a section ofsteel rail, a casting cast about said section of rail, so as to nclosethe web and support the flanges thereof, the under surface of the railbeing exposed to provide the upperface of the riser, substantially asdescribed.

4. A heel-riser comprising a steel rail and a casting cast about saidrail, so as to inclose the sides and support the flanges thereof, theunder surface of the rail being exposed, substantially as described.

5. A heel-riser comprising a section of rail, and a casting cast so asto surround the web and support the flanges of the rail, the undersurface of the base of the rail'constituting the upper face of theriser, ,substantially as described.

6. In a heel-riser, the combination with a IOO :eversed rail, of acasting arranged to inelose of its base shall be the upper face of theriser,

the Web and support the anges of the rail, of means arranged to supportthe anges of tlhe under surface of the base of the rail conthe rail,substantially as described.

stituting the upper face of the riser, substantially as described.Witnesses:

7. In a heel-riser, the combination with a M. E. SHIELDS,

reversed rail, arranged so that the under face F. H. DRURY.
